Airworthiness Directives; Turbomeca S.A. Turboshaft Engines 

AGENCY: Federal Aviation Administration (FAA), DOT. 

ACTION: Final rule; request for comments. 

SUMMARY: We are superseding airworthiness directive (AD) 2014-01-01 for all 

Turbomeca S.A. Arrius 2F turboshaft engines. AD 2014-01-01 required a one-time 

inspection of the ejector assembly nozzle of certain serial number (SIN) lubricating 

devices and, if a discrepancy was found, removal and replacement of the affected ejector 

assembly nozzle with a part eligible for installation. This AD requires the same action as 

AD 2014-01-01 and expands the list of affected SIN lubricating devices. This AD was 

prompted by the determination that additional lubricating devices, identifiable by SIN, 

may have an incorrect bonding of the nozzle on the ejector assembly. We are issuing this 

AD to prevent failure of the ejector assembly nozzle, which could lead to an in-flight 

shutdown (IFSD) of the engine, damage to the engine, and damage to the helicopter. 

DATES: This AD is effective [INSERT DATE 15 DAYS AFTER DATE OF 

PUBLICATION IN THE FEDERAL REGISTER]. 
The Director of the Federal Register approved the incorporation by reference of a

beginning of your comments. We specifically invite comments on the overall regulatory, 

3 
economic, environmental, and energy aspects of this AD. We will consider all comments

Discussion 

On January 2, 2014, we issued AD 2014-01-01 , Amendment 39-17724 (79 FR 

3481 , January 22, 2014), ("AD 2014-01-01 "), for all Turbomeca S.A. Arrius 2F 

turboshaft engines. AD 2014-01-01 required a one-time inspection of the ejector 

assembly nozzle of certain SIN lubricating devices and, if a discrepancy was found, 

removal and replacement of the affected ejector assembly nozzle with a part eligible for 

installation. AD 2014-01-01 resulted from an IFSD of an Arriel 1 engine. We issued AD 

2014-01-01 to prevent failure of the ejector assembly nozzle, which could lead to an 

IFSD of the engine, damage to the engine, and damage to the helicopter. 

Actions Since AD 2014-01-01 Was Issued 

Since we issued AD 2014-01-01 it has been determined that additional lubricating 

devices, identifiable by SIN, may have the same unsafe condition, an incorrect bonding of 

the nozzle on the ejector assembly. Also since we issued AD 2014-01-01, the European 

Aviation Safety Agency (EASA) has issued AD 201 5-0057, dated April 1, 201 5, which 

requires inspection, and replacement as necessary, of the affected lubricating devices. 

Related Service Information under 1 CFR Part 51 

We reviewed Turbomeca S.A. Mandatory Service Bulletin (MSB) No. 319 79 

4835, Version B, dated February 12, 2015. The MSB describes procedures for inspecting 

4 
the ejector assembly nozzle and, if necessary, replacing the ejector assembly nozzle. This 

service information is reasonably available; see ADDRESSES for ways to access this 

service information. 

FAA's Determination 

We are issuing this AD because we evaluated all the relevant information and 

determined the unsafe condition described previously is likely to exist or develop in other 

products of the same type design. 

AD Requirements 

This AD requires a one-time inspection of the ejector assembly nozzle of certain 

SIN lubricating devices and, for any ejector assembly nozzle that fails inspection, 

removal and replacement with a part eligible for installation. 

FAA's Justification and Determination of the Effective Date 

An unsafe condition exists that requires the immediate adoption of this AD. The 

FAA has found that the risk to the flying public justifies waiving notice and comment 

prior to adoption of this rule because of the short compliance time requirement. 

Therefore, we find that notice and opportunity for prior public comment are 

impracticable and that good cause exists for making this amendment effective in less than 

30 days. 

Costs of Compliance 

We estimate that this AD affects 96 engines installed on helicopters of U.S. 

registry. We also estimate that it will take about 1 hour per engine to comply with this 

AD. The average labor rate is $85 per hour. Required parts cost about $563 per engine. 

Based on these figures, we estimate the cost of this AD on U.S. operators to be $62,208. 

5 
Authority for this Rulemaking 

Title 49 of the United States Code specifies the FAA's authority to issue rules on 

aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. 

Subtitle VII, Aviation Programs, describes in more detail the scope ofthe Agency's 

authority. 

We are issuing this rulemaking under the authority described in Subtitle VII, 

Part A, Subpart Ill, Section 44701, "General requirements." Under that section, Congress 

charges the FAA with promoting safe flight of civil aircraft in air commerce by 

prescribing regulations for practices, methods, and procedures the Administrator finds 

necessary for safety in air commerce. This regulation is within the scope of that authority 

because it addresses an unsafe condition that is likely to exist or develop on products 

identified in this rulemaking action. 

Regulatory Findings 

This AD will not have federalism implications under Executive Order 13132. This 

AD will not have a substantial direct effect on the States, on the relationship between the 

national government and the States, or on the distribution of power and responsibilities 

among the various levels of government. 

For the reasons discussed above, I certify that this AD: 

(1) Is not a "significant regulatory action" under Executive Order 12866, 

(2) Is not a "significant rule" under DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979), 

(3) Will not affect intrastate aviation in Alaska to the extent that it justifies 

making a regulatory distinction, and 

6 
(4) Will not have a significant economic impact, positive or negative, on a 

substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Adoption of the Amendment 

Accordingly, under the authority delegated to me by the Administrator, the FAA 

amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: 

PART 39 -AIRWORTHINESS DIRECTIVES 

1. The authority citation for part 39 continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113,44701. 

§ 39.13 [Amended] 

2. The FAA amends§ 39.13 by removing airworthiness directive (AD) 2014-01-

01, Amendment 39-17724 (79 FR 3481, January 22, 2014), and adding the following new 

AD: 

2015-10-07 Turbomeca S.A.: Amendment 39-18163; Docket No. FAA-2013-1003; 

Directorate Identifier 2013-NE-33-AD. 

(a) Effective Date 

This AD is effective [INSERT DATE 15 DAYS AFTER DATE OF 

PUBLICATION IN THE FEDERAL REGISTER]. 

(b) Affected ADs 

This AD supersedes AD 2014-01-01, Amendment 39-17724 (79 FR 3481 , 

January 22, 2014). 

7 
(c) Applicability 

This AD applies to all Turbomeca S.A. Arrius 2F turboshaft engines. 

(d) Unsafe Condition 

This AD was prompted by the determination that additional lubricating devices, 

identifiable by serial number (SIN), may have an incorrect bonding of the nozzle on the 

ejector assembly. We are issuing this AD to prevent failure of the ejector assembly 

nozzle, which could lead to an in-flight shutdown of the engine, damage to the engine, 

and damage to the helicopter. 

(e) Compliance 

Comply with this AD within the compliance times specified, unless already done. 

(1) For engines equipped with a lubricating device having an SIN listed in Figure 

1 to paragraph (e) of this AD, within 30 days after the effective date of this AD, inspect 

the ejector assembly nozzle and the tightening torque. Use paragraphs 4.4.2.1 through 

4.4.2.3.4.2 ofTurbomeca Mandatory Service Bulletin (MSB) No. 319 79 4835, Version 

B, dated February 12, 2015, to do the inspection. 

(2) For any part that fails the inspection required by paragraph (e)(l) of this AD, 

before further flight, remove and replace the failed part with a part eligible for 

installation.
